To all. whom it n my concern:

Be it known that we, IsAAo W. GILES, of

TOBEY, of Fairhaven, in the county of Bris tol'and'State of Massachusettaboth citizens of the United'States, have invented a new and useful Improvementin the Manufacture and Application-of Rubber Tires to Wheel-- Rims, of whichthe following is a specifica tion.

View of same. v Heretofore' rubber tires have been molded,

then vulcanized,'and then placed on the rim, being held thereon by various means, such as place Fig. 1 2 is aplan cementing, binding-wires along the edge of the same, 850. By our invention we propose to mold the tire, directly on the rim, formed or shaped as shownin the various figures of the drawings. The tirethus molded is therrvul ,canized, the vulcanization being so regulated that the portion of tire immediately adjacent to the rim-is vulcanized to a degree of hard ness greater than the upper portion ofthe tire. Thus in Fig. 1 the portion of the tireunder the heads of the studs (1 is harder than the upper or tread portion of the tire B. The

studs aare secured to therim A, as shown:

By ourmethod of making 'and applying of special tools, now necessary, is done away with. i
